The project follows a skeptical female clinical psychologist (Westworld‘s Katja Herbers), a priest-in-training (Luke Cage star Mike Colter) and a blue-collar contractor as they investigate supposed miracles, demonic possessions and other extraordinary occurrences to see if there’s a scientific explanation or if something truly supernatural is at work.
Emerson — who won an Emmy for his work on Lost and recently recurred on Arrow — will play Townsend, an expert witness for the defense in a mass-murder case who might be an agent of evil.
